The following post comes to us from Miriam Schwartz-Ziv of the Department of Finance and Banking at the Hebrew University of Jerusalem.
In the paper, Does the Gender of Directors Matter?, which was recently made publicly available on SSRN, I investigate how having gender-balanced boards affects the working of boards. There has always been interest in the makeup of boards of directors, both in the academic literature and in the popular press. Lately, board diversity, and particularly the gender of directors has been a topic of much attention, since there is a recent movement to impose diversity requirements on boards. In the United States, the Securities Exchange Commission requires that companies disclose whether they have a diversity policy, and how it applies to board recruitment practices (Regulation S-K, Item 407(c)). In Europe, several countries (including Norway, France, Spain, and Italy) have already legislated laws enforcing gender quotas. Furthermore, Dr. Viviane Reding, the vice president of the European Commission, is promoting legislation enforcing gender quotas in all European countries (New York Times, March 4th, 2012).
Despite this attention, it nonetheless remains unclear whether diversity has a meaningful impact upon boards of directors, and how such impact might be measured. As emphasized by Hermalin and Weisbach (2003), board composition is jointly determined with firm performance, so it is problematic to draw inferences from the associations between firm performance and board composition. These scholars argue that instead of looking at the impact of boards on a firm’s overall financial performance, it is better to understand the impact of board composition by considering how it affects the actions the board or the firm take, given the board composition at the time the action is taken.
